Light is the opposite of darkness. While darkness is usually associated with sadness, loneliness, death and pain, light is more associated with hope, life and healing. When light is used as a guide in hypnosis, it can have a healing effect on depression, grief, pain or anxiety. Healing light is popularly used in hypnosis to enhance processes in the trance. It is suggested that healing light flows into the body with each inhale, bringing healing and relief, and that everything can be released with each exhale.
